Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] like Figures 1 to 3 As shown, this embodiment provides an electromagnetic pump for a kitchen appliance burner, including a pump body 3. The pump body 3 is provided with an oil inlet chamber 10, a first oil chamber 2, a pressure-stabilizing oil chamber 32, and a second oil chamber 13. The oil inlet chamber 10 is provided with an inlet 1, and an oil inlet connector is provided at the inlet 1 via a threaded connection. The specific size of the oil inlet connector can be selected according to the oil supply pipeline. One end of the oil inlet chamber 10 is connected to one end of the first oil chamber 2 via a first channel 11, and the other end of the first oil chamber 2 is connected to the pressure-stabilizing oil chamber 32 via a fifth channel 26. A one-way valve is provided between the first oil chamber 2 and the pressure-stabilizing oil chamber 32. The pressure-stabilizing oil chamber 32 is connected to the second oil chamber 13 via a sixth channel 27. A pressure-stabilizing component is provided on the pump body 3 and is connected to the pressure-stabilizing oil chamber 32. One end of the outer shell 5 is connected to the pump body 3, and the other end of the outer shell 5 is provided with an outlet 6. The electromagnetic component is provided inside the outer shell 5 and is located between the second oil chamber 13 and the outlet 6.

[0029] Pump body 3 is made of No. 3 zinc alloy and is treated with a nano double coating process, which has a super wear and corrosion resistant effect.

[0030] The one-way valve includes a one-way valve core 24 and a fourth elastic element 25. Under the elastic force of the fourth elastic element 25, the one-way valve core 24 blocks the first oil chamber 2, so that the fuel in the first oil chamber 2 can only flow into the pressure-stabilizing oil chamber 32 through the fifth channel 26, and cannot flow from the pressure-stabilizing oil chamber 32 into the first oil chamber 2.

[0031] The voltage stabilizing assembly includes a voltage stabilizing housing 28, a voltage stabilizing elastic element 29, a voltage stabilizing diaphragm 30, and a voltage stabilizing sealing ring 31. The voltage stabilizing housing 28 has an annular protrusion at one end facing the voltage stabilizing oil chamber 32. The voltage stabilizing sealing ring 31 is disposed between the outer wall of the annular protrusion and the inner wall of the voltage stabilizing oil chamber 32. The voltage stabilizing diaphragm 30 is disposed inside the voltage stabilizing housing 28. The voltage stabilizing elastic element 29 is disposed inside the voltage stabilizing housing 28 and located between the voltage stabilizing housing 28 and the voltage stabilizing diaphragm 30. More specifically, one end of the pressure-stabilizing housing 28 is open, and a snap-fit ​​ring is formed radially outward on the outer wall of the open end of the pressure-stabilizing housing 28. A fixing ring is fitted onto the open end of the pressure-stabilizing housing 28. A pressure-stabilizing port is provided on the side of the fixing ring facing the pressure-stabilizing oil chamber 32. The side of the fixing ring away from the pressure-stabilizing oil chamber 32 contracts towards the axis of the pressure-stabilizing housing 28 and wraps around the snap-fit ​​ring, so that the fixing ring can be connected to the pressure-stabilizing housing 28 through the snap-fit ​​ring. This creates an installation space between the pressure-stabilizing port and the interior of the pressure-stabilizing housing 28 for installing the pressure-stabilizing elastic element 29, the pressure-stabilizing diaphragm 30, and the pressure-stabilizing sealing ring 31. Furthermore, a snap-fit ​​sealing ring is also provided between the fixing ring and the snap-fit ​​ring to achieve a seal between the fixing ring and the pressure-stabilizing housing 28, preventing fuel leakage from the gap between the fixing ring and the snap-fit ​​ring.

[0032] The electromagnetic assembly includes an electromagnet 14, a moving iron core 20, a conduit 15, and a check valve. A through oil pressure channel is provided on the electromagnet 14 from the second oil chamber 13 to the outlet 6. The moving iron core 20, the conduit 15, and the check valve are arranged sequentially from the second oil chamber 13 to the outlet 6 within the oil pressure channel. A first elastic element 12 is provided between the moving iron core 20 and the second oil chamber 13, a second elastic element 19 is provided between the moving iron core 20 and the conduit 15, and a third elastic element 16 is provided between the conduit 15 and the check valve.

[0033] The outer casing 5 is equipped with a power interface. One end of the power cord 4 passes through the power interface and is electrically connected to the electromagnet 14 to supply power to the electromagnet 14. The other end of the power cord 4 is electrically connected to the control module, which outputs power at a certain frequency, enabling the electromagnet 14 to operate according to the parameters set in the control module, and enabling the electromagnetic pump to output fuel at the required pressure and flow rate.

[0034] A guide shaft is provided on the moving iron core 20 along the axial direction of the oil pressure channel. A guide hole is provided in the second oil chamber 13. The guide shaft is movably inserted into the guide hole. The first elastic element 12 is sleeved on the guide shaft. Thus, when the electromagnet 14 is energized or de-energized, the moving iron core 20 reciprocates relative to the second oil chamber 13. The first elastic element 12 can form a buffer between the moving iron core 20 and the pump body 3 to prevent the moving iron core 20 from directly colliding with the pump body 3.

[0035] The moving iron core 20 has four first through holes along the axial direction of the oil pressure channel. The four first through holes are evenly distributed around the guide shaft. When the moving iron core 20 reciprocates, the fuel in the second oil chamber 13 enters the conduit 15 through the first through holes and is finally ejected from the outlet 6 through the check valve.

[0036] Under the magnetic force of electromagnet 14, when the moving iron core 20 moves toward pump body 3, due to the obstruction of the one-way valve and pressure regulating component, the fuel between the moving iron core 20 and pump body 3 cannot flow toward inlet 1, but can only flow through the first through hole into conduit 15. When the moving iron core 20 moves away from pump body 3, since the sum of the cross-sectional areas of the four first through holes is less than the cross-sectional area of ​​the rest of electromagnet 14, the moving iron core 20 pushes the fuel to flow away from pump body 3. At this time, the cavity space between the moving iron core 20 and pump body 3 expands and the pressure decreases, so that the fuel in the inlet chamber 10 can overcome the elastic force of the fourth elastic element 25 in the one-way valve and enter the pressure stabilizing chamber 32 through the first oil chamber 2. The cavity space inside conduit 15 decreases and the pressure increases, which in turn increases the pressure around the check valve. The check valve opens, and the fuel with a certain pressure can flow to outlet 6.

[0037] The check valve includes a check valve block 17 and a check valve core 18. The check valve core 18 is located at the end of the check valve block 17 facing the outlet 6. The check valve block 17 has three second through holes along the axial direction of the oil pressure channel, serving as second channels 36. A third elastic element 16 is located between the guide tube 15 and the check valve block 17. Under the elastic force of the third elastic element 16, the check valve core 18 blocks the outlet 6, preventing fuel in the oil pressure channel from flowing out through the outlet 6. The check valve block 17 is made of stainless steel. A flow channel is provided on the check valve block 17 along the axial direction of the oil pressure channel. Multiple through holes penetrating the check valve block 17 are provided at the end of the flow channel facing the outlet 6, serving as second through holes. The check valve core 18 is made of an elastic material, such as polypropylene. The side of the check valve core 18 closest to the check valve block 17 has a larger projected area in the radial direction of the oil pressure channel, while the side of the check valve core 18 furthest from the check valve block 17 has a smaller projected area in the radial direction of the oil pressure channel. Thus, when the check valve core 18 is surrounded by pressurized fuel, the fuel pressure can push the check valve core 18 to overcome the elastic force of the third elastic element 16, open the outlet 6, and allow fuel to be sprayed out from the outlet 6.

[0038] The pump body 3 is also provided with a pressure regulating oil chamber 21, which is connected to the pressure stabilizing oil chamber 32 and the oil inlet chamber 10 respectively. A pressure regulating component is provided in the pressure regulating oil chamber 21.

[0039] The pressure regulating assembly includes a pressure regulating core 33, a pressure regulating block 34, a pressure regulating elastic element 35, and a pressure adjusting knob 9; the pressure regulating oil chamber 21 and the pressure stabilizing oil chamber 32 are connected through a third channel 22, and the pressure regulating oil chamber 21 and the oil inlet chamber 10 are connected through a fourth channel 23; the pressure adjusting knob 9 is threaded to the inner wall of the pressure regulating oil chamber 21, and the pressure adjusting elastic element 35, the pressure regulating block 34, and the pressure regulating core 33 are sequentially arranged between the pressure adjusting knob 9 and the third channel 22, and the pressure regulating core 33 blocks the third channel 22 under the pressure of the pressure regulating elastic element 35. The pressure regulating block 34 is made of brass. One end of the pressure regulating block 34 is recessed inward along its axial direction to install the pressure regulating core 33. The pressure regulating core 33 is made of an elastic material, such as polypropylene. The side of the pressure regulating core 33 facing the third channel 22 has a hemispherical concave structure and is coaxially arranged with the third channel 22. While blocking the third channel 22, it can allow the high-pressure fuel from the third channel 22 to diffuse along the hemispherical surface, which can reduce the impact of high-pressure fuel on the pressure regulating chamber 21, disperse the pressure of high-pressure fuel, reduce pressure fluctuations in the pressure regulating chamber 21 and the pressure stabilizing chamber 32, and further improve the pressure stability of the fuel injected from the outlet 6. By adjusting the depth of the pressure regulating knob 9 into the pressure regulating chamber 21, the preload of the pressure regulating elastic element 35 is changed, thereby changing the clamping force of the pressure regulating block 34 on the pressure regulating core 33, and thus adjusting the maximum pressure in the pressure stabilizing chamber 32.

[0040] The pump body 3 is provided with an exhaust chamber. One end of the exhaust chamber is connected to the pressure stabilizing oil chamber 32, and the other end of the exhaust chamber is provided with an exhaust port 8. An exhaust assembly is provided inside the exhaust chamber.

[0041] The venting assembly includes a venting knob 7 and a venting sealing ring. The venting sealing ring is located inside the venting chamber and between the venting port 8 and the pressure-stabilizing oil chamber 32. The venting knob 7 is threadedly connected to the inner wall of the venting chamber, and one end of the venting knob 7 inside the venting chamber contacts and seals with the venting sealing ring. When it is necessary to vent the pump body 3, the venting knob 7 is loosened to separate it from the venting sealing ring. The gas inside the pump body 3 flows out through the venting sealing ring and is discharged to the outside of the pump body 3 through the venting port 8. After venting is completed, the venting knob 7 is tightened again.

[0042] The first elastic element 12, the second elastic element 19, the third elastic element 16, the fourth elastic element 25, the pressure stabilizing elastic element 29, and the pressure regulating elastic element 35 are all helical springs.
